Focal
cortical grey matter lesions (CLs) are an important component of multiple sclerosis
(MS) pathology. However, detecting cortical lesions in MS using MRI poses
challenges. MRI at ultra-high field strengths such as 7 Tesla has the
potential to superbly enhance MS-induced CLs visibility. In this study, we
applied ultra-high resolution R2* maps to detect and evaluate cortical
lesions and their subtypes and the MRI results were compared with the
pathology analysis.
